Yes, if you have a char (1byte) pointer and you ++, you'll get one byte 
further. If you have a short (2byte) you'll get two bytes further in 
memory. If you have a long (4byte) pointer, you'll get 4 bytes further 
in memory if you ++.

It is simular to dealing with arrays (looking at the memory layout)

If you have an array of structs and need to get to the next struct in 
the array then you will need to look sizeof(struct) further in memory to 
find the next item in the array.
